PLANEE.

Application filed April 29, 1921. Serial No. 465,594.

T 0 all whom it may concern:

Belt known that I, JAY E. Lmaarama citizen of the United States, residing at Canton, in the county or Stark and State of Ohio, have invented anew and useful Planer, of which the following is a specification.

This invention relates to planers and has for its objects the provision of a planer in which a driving motor is carried upon the upper end of the column, thus producing a separate unit having a self-contained drive;

other objects being the provisionof means whereby the belt, connecting the drive pulley of the motor with the drive mechanism of the planer, may be held taut at all times."

With these objects in View, the invention consists in the construction and arrangement of parts hereinafter described and illustrated in the accompanying drawing, it being un derstood that changes in the form and details of construction may be made without departing from the appended claims The invention thus set'forth in' general terms is illustrated in the accompanying drawings in which, s

Figure 1 is a perspecti ve vie-w of a planer embodying the invention;

ciprocating table 2 arranged to be reciprocated longitudinally upon said base by suitable mechanism, the work being clamped upon said table in the usual manner.

The column 3 is shown located upon the operators side of the table in order that work which is considerably wider than the table may project beyond the opposite edge of the table and thus not interfere with the operator, whose position. is upon the side of the machine adjacent the column in proper position to control the different operating levers and wheels and the switch which con-' trols the motor.

The arm 4 is mounted upon the column 3 and extended over the table 2 and arranged to be raised and lowered upon the-column in the usual mannenthe raising and lowering means being controlled by the shaft 5 which may be rotated by any suitable tool when it is desired to adjust the arm vertically upon the column.

. The tool head 6 mountedupon the arm 4 and arranged to be moved laterally "thereon by means of the usual screw threaded shaft 7, this shaft having a squared extremity 8 to which a crank or similar tool may be applied for operating the cross feed.

The vertical feed of the tool is controlled.

through the shaft 9 which is also provided with a squared extremity 10 for the reception of a crank or the like. Theusual gearing which is operated through the shaft 9,

cooperates with the'rack ll to produce the vertical feed.

The mechanism for reciprocating the table is operatively connected to'the'pulley l2 and for the purpose of driving said pulley, 1a

motor 13 is mounted uponjthe upper end of the column 3, the pulley 14 ofsaid motor being connected to the belt 15.

As the belt 15 is suspended'in a substantially vertical position between the pulleys 12 and 14, it is desirable that some means the pulley 12 by means of be provided for keeping the belt stretched tight between said pulleys and 'for this purpose the motor 13 is fixed upon the hinged plate 16' as by meansof the screws 17, said plate being hinged along one side edgeto the upper end of thecolumn' 8 as shown at 18.

plate 16' and engage the upper surface of the column 3.

If at any time the. belt becomes loose, the slack may be immediately taken up by adjusting the screws 19 to swing the plate 16 upwardly upon. its hinge, raising the pulley 14 of the motor, thus lengthening the distance between said pulley and the pulley 12, thus tightening the belt,

For the purpose or changing the speed of the table 2, suitable speed'changing mech anism is provided within the base 1 and operated by the levers 20 and 21; Suit- Adjusting screws 19 are threadedthrough the opposite edge portion of the able mechanism for locking the table- 7 against movement is also provided and arranged to' "be controlled by the hand wheel 22.

From the above description it will be'evident that a planer is provided having a self-contained driving mechanism by means or which the planer forms a separate unit which ina yi be placed in any location and operated Without the necessity of attaching to a line shaft or other driving means. All of the controlling mechanism for operating the different parts of the planer, as Well as the switch which controls the motor, are located in position to be easily accessible to the operator of the planer without the necessity of reaching over or walking around the planer.

The motor is mounted upon the top of the column and the belt connecting the motor pulley to the drive pulley of the planer is located uponthe side of the column away from the table, thus not interfering With the operation of the planer and a simple and cfiiciem means is provided for preventing any slack in the belt and holding the same tight at all times.

1. In a planer comprising a base a reciprocating table thereon and tical column provided at one side ot the base, and a drive pulley connected to the driving mechanism of the table, a plate upon the column, a motor mounted upon said plate, and adjusting screwst'or raising the plate to tighten said belt.

.2. In a planer comprising a base having having a vera reciprocating table thereon and a vertical colnx'iin provided at one'side of the base, and a d ive pulley connected to the driving mechanism of the table, a motor mounted upon the upper end or" the column, a belt connecting aid motor to said drive pulley and means for raising said motor to tighten said belt.

3. In a planer comprising a base having a reciprocating table thereon and a vertical column provided at one side of the base, and a drive pulley connected to the driving mechanism of the table amotor hingedly mounted upon the upper end of the col umn, a belt connecting said motor to said drive pulley and means for tilting the motor upon its hinge to tighten said belt.

4. In a planer comprising a base having a reciprocating table tl'iereon and a vertical column provided at one side of the base and a drive pulley connected to the driving mechanism of the table, a plate hinged at one edge to the outer end of the column, a motor mounted upon said plate, a belt connecting said motorto said drive pulley, and adjusting screws located through the fre edge portion of the plate for tightening said belt. 7

In testimony that I claim the above, I have hereunto subscribed my name.
